Description

TECHNICAL FIELD

The present invention relates to a pharmaceutical injection device that injects growth hormone or another such pharmaceutical, for example, and to a medical support system in which this device is used.

BACKGROUND ART

For example, a pharmaceutical injection device that injected growth hormone or the like had a configuration comprising a main body case, a piston that pushed the pharmaceutical contained in this main body case out through an injection needle and into the patient's body, a drive motor that drives the piston, a first controller connected to this drive motor, and a memory connected to this first controller.
Since data related to the pharmaceutical injection amount set by a physician, for example, is stored in the memory of the pharmaceutical injection device, when the patient actuates the drive motor, the piston is driven on the basis of this data and the set pharmaceutical is injected into the patient's body.
Since the data related to the pharmaceutical injection amount is set by a physician or the like, the patient must bring the pharmaceutical injection device to the physician's office when receiving treatment, but patients often forget to bring the pharmaceutical injection device, in which case the data cannot be changed until the patient sees the physician the next time.
For example, a patient who injects growth hormone will normally go the doctor only once every few months, and this is undesirable because the above-mentioned data change will not be done until several months later.
In view of this, it has been proposed that this data change be executed via a mobile communication device.
Specifically, the configuration is such that when change data is transmitted wirelessly from the doctor's medical equipment input apparatus to the patient's mobile communication device, this mobile communication device can immediately transmit data for changing the pharmaceutical injection amount to the pharmaceutical injection device (as conventional art related to this, see, for example, Patent Literature 1 below).

SUMMARY

TECHNICAL PROBLEM

The above-mentioned conventional art involves measuring a blood glucose level and then changing the insulin injection amount in real time on the basis of this blood glucose level. To this end, the mobile communication device and the pharmaceutical injection device must be kept in a communicable state at all times, and as a result, the power consumption expense of the pharmaceutical injection device rises. Accordingly, a power supply with a large capacity must be used with the pharmaceutical injection device. As a result, the pharmaceutical injection device ends up being larger, which makes it less convenient to use.
It is therefore an object of the present invention to make such a device easier to use.

SOLUTION TO PROBLEM

To achieve this object, the present invention is configured to comprise a main body case, a piston that pushes a pharmaceutical contained in the main body case out through an injection needle and into the patient's body, a drive motor that drives the piston, a first controller that is connected to the drive motor, a memory and a first near field communication component that are connected to the first controller, and a battery that supplies power to the drive motor, the first controller, the memory, and the first near field communication component, wherein the first controller receives change data pertaining to the amount of drive by the drive motor from a mobile communication device through the first near field communication component, records the change data in the memory, and sends the execution of change data, as the change data reception status, back to the mobile communication device through the first near field communication component, thus achieving the stated object.
Specifically, with the present invention the configuration is such that change data for the drive amount by the drive motor is received from a mobile communication device via a near field communication component, this change data is recorded in a memory, and the execution of change data is sent as the change data reception status back to the mobile communication device via the near field communication component, so there is no need for connecting to the mobile communication device in real time.
Therefore, the pharmaceutical injection device consumes less power, so there is no need for a large-capacity battery to be used with the pharmaceutical injection device, and as a result the pharmaceutical injection device can be more compact, which makes it easier to use.

ADVANTAGEOUS EFFECTS

The present invention provides a pharmaceutical injection device that is compact and easy to use.

DESCRIPTION OF EMBODIMENTS

Embodiments of the present invention will now be described in detail through reference to the drawings.

Embodiment 1

FIG. 1 shows the medical support system in an embodiment of the present invention. The medical support system 100 in this embodiment comprises a pharmaceutical injection device 1 (an example of medical equipment used by a patient 4), a mobile communication device 2 that acquires usage information about this pharmaceutical injection device 1, and a personal computer 5 (an example of a medical equipment input apparatus) to which the usage information about the pharmaceutical injection device 1 is transmitted from the mobile communication device 2 via a network 3.

Pharmaceutical Injection Device

As shown in FIGS. 2 and 3, the pharmaceutical injection device 1 is designed so that the state in FIG. 4 results when a cover 7 of a main body case 6 is opened up, a pharmaceutical syringe 8 is mounted, and an injection needle 10 is mounted to the distal end of this pharmaceutical syringe 8.
That is, in the state of the pharmaceutical injection device 1 shown in FIG. 4 (in which the pharmaceutical syringe 8 is mounted and the cover 7 is closed), the pharmaceutical inside the pharmaceutical syringe 8 can be injected from the injection needle 10 at the distal end into the patient's body by pushing a piston 9 into the pharmaceutical syringe 8.
In this embodiment, the pharmaceutical contained in the pharmaceutical syringe 8 is, for example, a pharmaceutical such as a growth hormone that is injected by the patient 4 (FIG. 1), who suffers from growth hormone deficiency dwarfism, into his own body.
In order to perform this operation of injecting a growth hormone, this pharmaceutical injection device 1 comprises a power switch 11, an inject switch 12, an OK button 13a, a down button 13b, and an up button 13c. As shown in FIG. 5, these are configured to be connected to a controller 14.
A drive motor 15 for driving the piston 9 is also connected to this controller 14 via a motor drive circuit 16.
A current sensing circuit 17 is connected to the motor drive circuit 16, and this current sensing circuit 17 is also connected to the controller 14.
This current sensing circuit 17 detects a major change in the drive current of the motor drive circuit 16 supplying drive current to the drive motor 15, when a large load is applied to the drive motor 15 for one reason or another, or when the drive motor 15 malfunctions, etc. When the current sensing circuit 17 detects an abnormal change in current, the pharmaceutical injection device 1 is configured to notify the controller 14 of this abnormality so that appropriate action can be taken.
More specifically, when an over-current or other such abnormal current change is detected by the current sensing circuit 17, this signal is sent to the controller 14. Upon inputting this, the controller 14 issues a command such as an emergency stop to the motor drive circuit 16, and having receiving this emergency stop command, the motor drive circuit 16 subjects the driver motor 15 to an emergency stop.
Also, an encoder 18 is connected to the drive motor 15, and this encoder 18 is also connected to the controller 14.
That is, the operation of the piston 9 is executed by the drive motor 15 while information about the position of the piston 9 is checked by the encoder 18.
A memory 19 that holds operating programs is also connected to the controller 14.
Furthermore, a communication component 20 that performs near field communication (the "NFC IC" in the example in FIG. 5) is connected to this controller 14, and a memory 21 that holds usage information about the pharmaceutical injection device 1 is connected to the communication component 20. 22 in FIG. 5 is a battery used to execute the operation of the various components shown in FIG. 5.
23 is a display component that displays the input method, etc. 24 is a needle detector switch that detects the mounting of the injection needle 10. 25 is a syringe detector switch that detects the mounting of the pharmaceutical syringe 8.
The display component 23, the needle detector switch 24, and the syringe detector switch 25 are each connected to the controller 14.

Mobile Communication Device

As shown in FIG. 6, the mobile communication device 2 shown in FIG. 1 has a communication component 26 for communicating with a personal computer server (not shown) or another network or for making telephone calls. This communication component 26 is connected to a controller 27.
As is well known, a mobile communication device 2 such as this comprises a display component 28, a touch panel 29 that serves as the interface and is displayed in the display component 28, a power switch 30, a position information sensor 31 (GPS in the example in FIG. 6), a sounder 32 that gives audible output (such as voice output), a memory 33 that holds operating programs for executing the operation of the various components, setting data, usage information for the pharmaceutical injection device 1, and so forth, and a battery 34 for operating the various components.
The display component 28, the touch panel 29, the power switch 30, the position information sensor 31 (GPS in the example in FIG. 6), the sounder 32, and the memory 33 are connected to the controller 27.
Also, an acceleration sensor 35, a brightness sensor 36, a microphone 37, and a communication component 38 that performs near field communication (an NFC IC in the example in FIG. 6) are each connected the controller 27.
The characteristic features of this embodiment, as shown in FIG. 6, is that the communication component 38, which is used for performing near field communication with the communication component 20 of the pharmaceutical injection device 1, is connected to the controller 27 of the mobile communication device 2.
That is, usage information about the pharmaceutical injection device 1 is transferred to the mobile communication device 2 by near field communication (executed by close proximity) between the communication component 20 and the communication component 38 of the mobile communication device 2.

Personal Computer

The personal computer 5 shown in FIG. 1 will now be described. This personal computer 5 is owned by a doctor.
As shown in FIG. 7, the personal computer 5 has a communication component 39 that communicates with the communication component 26 of the mobile communication device 2 via the network 3, etc., a controller 40 that is connected to this communication component 39, and a memory 41 that is connected to this controller 40.
Also, a display device 42, an interface device 43, and an external memory device 44 are connected to the controller 40.
Furthermore, this controller 40 is connected to a communication component 45 (an NFC IC in the example in FIG. 7) for performing near field communication (executed by close proximity) with the communication component 38 of the mobile communication device 2 or near field communication with the communication component 20 of the pharmaceutical injection device 1.

Medical Support Method

With the above configuration, the drive amount of the drive motor 15 (see FIGS. 4 and 5) of the pharmaceutical injection device 1 is held in the memory 19 (see FIG. 5). This drive amount corresponds to the amount of pharmaceutical to be injected into the patient. That is, the pharmaceutical injection amount for the patient 4 is held in the memory 19, and this injection amount is data set by a doctor at a hospital and stored in the memory 19. The patient 4 injects the pharmaceutical each time by using the pharmaceutical injection device 1 on the basis of the injection amount data set by the hospital doctor and stored in the memory.
Let us say that the patient 4 goes to the doctor once every three months, and after being examined by the doctor, his data is updated by the doctor and stored in the memory 19 according to his physical condition at the time of that visit. Therefore, the patient 4 has to bring the pharmaceutical injection device 1 to the doctor's office for each appointment. However, the patient may sometimes forget to bring the pharmaceutical injection device 1.
In this embodiment, this update data (the newly set pharmaceutical injection amount) is stored by the doctor in the memory 33 (see FIG. 6) of the mobile communication device 2 carried by the patient 4, so the patient 4 can transfer this update data to the pharmaceutical injection device 1 at home, where it can be used as the pharmaceutical injection amount from that point on.
The following description, with reference to the drawings, will be of a method for setting and updating a new pharmaceutical injection amount by a doctor, a method for setting and updating update data for the injection amount in the pharmaceutical injection device 1 by the patient 4 at home after it has been set and updated by the doctor, and so forth.
FIGS. 8 and 9 show a state in which the personal computer 5 is used by a doctor at a hospital to update the pharmaceutical injection amount for a patient 4.
First, in FIG. 8, the operator's (in this case, the doctor's) ID and password are inputted using with the display device 42 of the personal computer 5 (see FIG. 7). If the operator ID and password are correct, next, an injector setting tool screen (an equipment setting screen used by the doctor) is displayed on the screen of the display device 42 as shown in FIG. 9.
Patient data is updated on this equipment setting screen by the doctor. That is, as shown in FIG. 9, since the height and weight of a patient 4 vary at the time of examination, the correct pharmaceutical injection amount is changed to match the condition of that patient 4.
There is usually one pharmaceutical injection device 1 for each patient, with that device being used only for that patient.
Next, what is displayed on the injector setting tool screen (an equipment setting screen used by the doctor) of the display device 42 in FIG. 9 will be briefly described.
The injector setting tool screen displays, starting from the top, the "prescription management-use prescription number," "patient ID" (a unique code for identifying the patient 4), "birth date" (the birth date of the patient 4), "height" (data about the height of the patient 4), "weight" (weight data for the patient 4), "dosage" (this indicates the pharmaceutical injection amount), "start of notification" (this indicates the date on which a notification message is given for the setting expiration or the setting implementation date; shown as "one day before" in FIG. 9), "setting change/start date" (this indicates the date when the setting is changed, and no change can be made until this start date), "setting change/expiration date" (this indicates the expiration date by which the setting can be changed, and the setting cannot be changed after this date), "email address: doctor" (the email address of the doctor, which is used to send injection amount setting data and the like and to receive notifications about whether or not to execute setting and changing the injection amount), "email address: patient" (the email address of the patient, which is used to send notifications about whether or not to set and change the injection amount, and to receive injection amount change data and the like from the doctor), and so forth.
The data setting and change of the pharmaceutical dose (injection amount) may involve direct input and setting when the doctor has determined the condition of the patient, or may be performed on the basis of the age, height, and weight of the patient.
In this example, the date on which the setting change can be started is February 10, 2014, and the expiration date by which this change can be made is February 13, 2014. In addition, the email addresses of the doctor and patient 4 are set.
Therefore, the pharmaceutical dose set with the personal computer 5 is sent by email from the personal computer 5 to the mobile communication device 2 of the patient 4 (S101 in FIG. 10). This S101 corresponds to an example of a first transmission step.
Since the operation by which the pharmaceutical dose is sent from the personal computer 5 to the mobile communication device 2 is the same as in the above-mentioned patent literature, it will be omitted here to keep the description from becoming too complicated.
Upon receiving an email, the controller 27 of the mobile communication device 2 causes the display component 28 to display a screen indicating that an email has been received (S1 in FIG. 10).
The controller 27 then puts the equipment setting change data (such as update data about the pharmaceutical injection amount) received in this email in a folder located in the memory 33 of the mobile communication device 2 (S2 in FIG. 10). The controller 27 then reads from this email the changed pharmaceutical dose setting (injection amount), the setting change start date, the setting change expiration date, and so forth (S3 in FIG. 10).
After this, when February 9, 2014 arrives, the controller 27 of the mobile communication device 2 causes the display component 28 to give the display shown in FIG. 11 (S4 in FIG. 10).
That is, as shown in FIG. 9, since the doctor uses the personal computer 5 to set the notification for a setting change to one day before, when February 9 arrives, as shown in FIG. 11, the controller 27 causes the display component 28 to display a message prompting the user to change the setting of the dose (S5 in FIG. 10).
In the example in FIG. 11, the display shows that the date on which the pharmaceutical dose setting is to be changed will be the following day (February 10, 2014).
That is, the patient is notified that starting on February 10, 2014 (the next day), the pharmaceutical dose setting (injection amount) can be changed, and is advised to be ready for this.
Therefore, when February 10, 2014 arrives, the patient 4 brings the mobile communication device 2 into close proximity with the pharmaceutical injection device 1 and executes the above-mentioned change of the pharmaceutical dose. That is, change data about the pharmaceutical injection amount is transferred from the communication component 38 of the mobile communication device 2 to the communication component 20 of the pharmaceutical injection device 1, and this newly changed pharmaceutical injection amount data is stored in the memory 19 (S6 in FIG. 10).
Therefore, from that point on, the pharmaceutical injection device 1 will execute pharmaceutical injection on the basis of the newly changed pharmaceutical dose (injection amount) stored in the memory 19.
Also, the mobile communication device 2 sends the personal computer 5 a notification to the effect that change data for the pharmaceutical injection amount was transferred to the pharmaceutical injection device 1.
Specifically, in this embodiment, change data about a new pharmaceutical injection amount corresponding to the drive amount of the drive motor 15 is received from the mobile communication device 2 via the communication component 20 of the pharmaceutical injection device 1 and the communication component 38 of the mobile communication device 2 (performing near field communication), this change data is recorded in the memory 19 of the pharmaceutical injection device 1, and the result of this change data for the pharmaceutical injection amount being received is sent back to the mobile communication device 2 via the communication components 20 and 38 (performing near field communication). Because of this configuration, there is no need for the pharmaceutical injection device 1 to be connected in real time to the mobile communication device 2.
Therefore, the pharmaceutical injection device 1 consumes less power, so there is no need for a large-capacity battery 22 to be used with the pharmaceutical injection device 1, and as a result the pharmaceutical injection device 1 can be made more compact, which makes it more convenient to use.
In contrast, if the patient 4 does not send update data for the pharmaceutical injection amount to the pharmaceutical injection device 1 even though the setting change expiration by which data update is to be performed (indicating that the setting change start date for the pharmaceutical dose (the injection amount) has passed) has arrived, the controller 27 of the mobile communication device 2 causes the display component 28 to give the display shown in FIG. 12. As shown in FIG. 12, the display component 28 displays an enter key 28a (also called an OK key) and a cancel key 28b.
That is, in the example in FIG. 9, since the setting start date made by the doctor is February 10, 2014, and the setting change expiration is February 13, 2014, FIG. 12 shows the display state outputted on February 12, 2014. This display includes information indicating that the setting change expires on February 13, and that the setting can be changed for only one more day, and prompts the user to move the mobile communication device 2 and the pharmaceutical injection device 1 close together to change the setting of the pharmaceutical dose. The display shown in FIG. 12 corresponds to an example of a first message.
The controller 27 of the mobile communication device 2 causes the display component 28 to give the display shown in FIG. 13 on the expiration date (the following day) when update data has not been transferred from the mobile communication device 2 to the pharmaceutical injection device 1 despite the fact that the display in FIG. 12 was shown on the display component 28 (S7 in FIG. 10).
That is, in FIG. 13, the patient 4 is advised that the level of urgency is higher than in the state in FIG. 12, so the display color of the message displayed in the upper part of the display device 42 is changed to a color that stands out more than the display in FIG. 12.
More specifically, the background of the setting change message box is changed to a dark color (such as red or navy blue), and the text is changed to a light color (such as white or a pastel color), so as to make it easy to see at a glance that the setting expiration is approaching. That is, a notification is given by visual effect.
In this display it is shown that the setting change expiration is today (February 13), and that the mobile communication device 2 should be moved close to the pharmaceutical injection device 1.
When February 14 arrives, the setting change expiration has already passed, so the controller 27 causes the display component 28 to give the display shown in FIG. 14. The display in FIG. 14 corresponds to an example of a second message.
That is, the display tells the user that the change data for the pharmaceutical injection amount was not updated within the setting change period, and a notification that the update could not be performed to the doctor by e-mail, and advises the user to go to see the doctor.
A message to the effect that the change data was not updated is then sent from the mobile communication device 2 to the personal computer 5.
On the other hand, if the change data has been updated, the fact that the change data was updated is sent from the mobile communication device 2, through the network 3, to the personal computer 5 (S8 in FIG. 10).
The personal computer 5 receives notice of whether or not the change data was updated, over a network by email or the like (S102 in FIG. 10).
Here, the display content upon receipt by the personal computer 5 is displayed on the display device 42, and an example of this is shown in FIGS. 16 and 17.
Specifically, the display content of the display device 42 shown in FIG. 16 shows the display when change data for the dose has been set in the pharmaceutical injection device 1 used by the patient 4, and displays the patient ID and patient name for the changed dose, the date of the change, patient information, the set dose, and the like, as well as a message to the effect that there has been a change.
The display content of the display device 42 shown in FIG. 17 is displayed when no dose change data was set, and displays the patient ID, patient name, prescription number, information related to change details and the like scheduled to be changed, as well as a message to the effect that there has been a change.
Just as in the case of FIG. 13, the display color of the message display portion is selected to be a color that stands out visually, to tell the patient 4 that action is urgently needed.
Next, the data update will be described. FIG. 15 is a flowchart of the operation during data update.
To update the data for the pharmaceutical dose, the patient 4 moves the mobile communication device 2 close to the pharmaceutical injection device 1 and hits the enter key 28a (OK key) shown in FIG. 12, whereupon change data about the pharmaceutical dose is sent from the communication component 38 of the mobile communication device 2 to the communication component 20 of the pharmaceutical injection device 1 (S11 in FIG. 15).
S11 in FIG. 15 corresponds to an example of a second transmission step.
When the pharmaceutical injection device 1 receives the change data (S21 in FIG. 15), the change data for the pharmaceutical dose is stored in the memory 19 of the pharmaceutical injection device 1 (S22 in FIG. 15).
S22 in FIG. 15 corresponds to an example of an execution step. Storage in the memory 19 corresponds to an example of the execution of change data.
Next, the pharmaceutical injection device 1 sends information indicating that data was stored in the memory 19 and change data was set back to the mobile communication device 2 (S23 in FIG. 15). S23 in FIG. 15 corresponds to an example of a third transmission step.
Upon receiving the execution information, the mobile communication device 2 determines that the update of data is complete, and as shown in S8 in FIG. 10, information indicating that the update of data is complete is sent over the network 3 to the personal computer 5.
Thus, the mobile communication device 2 can confirm the completion of the update of data in the pharmaceutical injection device 1 by receiving a reply from the pharmaceutical injection device 1, and the doctor can manage the pharmaceutical dose for the patient 4 by sending the confirmation result back to the personal computer 5.

Main Features

(1)
The pharmaceutical injection device 1 in this embodiment comprises the main body case 6, the piston 9, the drive motor 15, the controller 14, the memory 19, the communication component 20, and the battery 22 (see FIGS. 4 and 5).
The piston 9 pushes the pharmaceutical contained in the main body case 6 out through the injection needle 10 and into the patient's body. The drive motor 15 drives the piston 9. The controller 14 is connected to the drive motor 15.
The memory 19 is connected to the controller 14. The communication component 20 is connected to the controller 14. The battery 22 supplies power to the drive motor 15, the controller 14, the memory 19, and the communication component 20.
The controller 14 receives change data for the modification data of the drive motor 15 from the mobile communication device 2 via the communication component 20, records the change data in the memory 19 of the pharmaceutical injection device 1, and sends information about the execution of the change data through the communication component 20 back to the mobile communication device 2, as the reception state of the change data.
Also, change data can be transmitted by moving the mobile communication device 2 close to the pharmaceutical injection device 1, so the pharmaceutical injection device 1 does not have to be connected in real time to the mobile communication device 2.
Consequently, the power consumption of the pharmaceutical injection device 1 is far lower than when connected in real time, so there is no need to provide a large-capacity battery to the pharmaceutical injection device 1, and as a result, the pharmaceutical injection device 1 can be made more compact, which improves portability and makes the device more convenient to use.
(2)
Also, the medical support method in this embodiment is a medical support method for changing the pharmaceutical injection amount of the pharmaceutical injection device 1, comprising S101 in FIG. 10 (an example of a first transmission step), S13 (an example of a second transmission step), S22 (an example of an execution step), and S23 (an example of a third transmission step) in FIG. 15, and S8 in FIG. 10 (an example of a fourth transmission step).

In S101 in FIG. 10 (an example of a first transmission step), the change data received from the personal computer 5 is transmitted to the mobile communication device 2.
In S13 in FIG. 15 (an example of a second transmission step), change data is transmitted from the mobile communication device 2 to the pharmaceutical injection device 1 by means of near field communication through the communication component 38 of the mobile communication device 2 and the communication component 20 of the pharmaceutical injection device 1.
In S22 in FIG. 15 (an example of an execution step), the setting of change data is executed at the pharmaceutical injection device 1.
In S23 in FIG. 15 (an example of a third transmission step), information about the execution (an example of the execution of change data) of the storage of change data in the memory 19 (of the pharmaceutical injection device 1) by near field communication is transmitted from the pharmaceutical injection device 1 to the mobile communication device 2.
In S8 in FIG. 10 (an example of a fourth transmission step), the execution or non-execution of change data (including whether or not the change data is updated) is transmitted from the mobile communication device 2 to the personal computer 5.
Because change data can be transmitted by moving the mobile communication device 2 close to the pharmaceutical injection device 1, there is no need to connect in real time to the mobile communication device, so the pharmaceutical injection device can be made more compact, which improves its portability and so forth, and makes it more convenient to use.
Also, a health care provider can ascertain whether or not the patient has updated the change data, and can therefore manage the pharmaceutical injection amount. Other Embodiments

(A)
The above embodiment dealt only with a situation in which the display on the mobile communication device 2, etc., was used to warn or caution the patient 4, but the sounder 32 shown in FIG. 6 can be used to sound an alarm in conjunction with the above-mentioned display, or the timbre can be varied to warn or caution the patient 4 with a hearing effect.
(B)
In the above-mentioned embodiment, an example was given of a medical support system that included a pharmaceutical injection device or the like that made use of a growth hormone pharmaceutical, but this is not the only option, and it should go without saying that the present invention can be applied to all cases in which a pharmaceutical is administered at regular intervals, such as for osteoporosis.
(C)
Also, in the above description, an example was given of using the pharmaceutical injection device 1, the mobile communication device 2, and the personal computer 5 used by a doctor, but change data can also be sent and received directly between the personal computer 5 and the pharmaceutical injection device 1 through near field communication (NFC).
